1. Suffering is a trial that reveals our vulnerability yet, if we allow it, also opens the door to the power of Christ.
"Suffering, in fact, is always a trial—at times a very hard one—to which humanity is subjected. The gospel paradox of weakness and strength often speaks to us from the pages of the Letters of Saint Paul, a paradox particularly experienced by the Apostle himself and together with him experienced by all who share Christ's sufferings. Paul writes in the Second Letter to the Corinthians: 'I will all the more gladly boast of my weaknesses, that the power of Christ may rest upon me'. In the Second Letter to Timothy we read: 'And therefore I suffer as I do. But I am not ashamed, for I know whom I have believed'. And in the Letter to the Philippians he will even say: 'I can do all things in him who strengthens me'" - St. John Paul II
2. Human suffering united to the Cross of Jesus has supernatural value.
"Those who share in Christ's sufferings have before their eyes the Paschal Mystery of the Cross and Resurrection, in which Christ descends, in a first phase, to the ultimate limits of human weakness and impotence: indeed, he dies nailed to the Cross. But if at the same time in this weakness there is accomplished his lifting up, confirmed by the power of the Resurrection, then this means that the weaknesses of all human sufferings are capable of being infused with the same power of God manifested in Christ's Cross. In such a concept, to suffer means to become particularly susceptible, particularly open to the working of the salvific powers of God, offered to humanity in Christ. In him God has confirmed his desire to act especially through suffering, which is man's weakness and emptying of self, and he wishes to make his power known precisely in this weakness and emptying of self." - St. John Paul II
3. Suffering united to Jesus can be accompanied by spiritual comfort, love and even joy.
God releases great spiritual power through our co-redemptive suffering. Like the saints, we contribute to the conversion of souls, and bring many people to Christ through the offering of our daily sufferings—especially for priests who are charged by God to give the sermons that transmit the faith. St. Thérèse of Lisieux once wrote, “Sufferings gladly borne for others convert more people than sermons.” Once we understand how co-redemptive suffering can help souls and build up the Kingdom of God, we can experience consolation, love and even joy:
"Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. For as we share abundantly in Christ’s sufferings, so through Christ we share abundantly in comfort too. If we are afflicted, it is for your comfort and salvation; and if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer. Our hope for you is unshaken; for we know that as you share in our sufferings, you will also share in our comfort." - St. Paul (2 Corinthians: 3-7)
4. The Blessed Virgin Mary is the Mother of Sorrows and a source of tremendous consolation as we face the crosses of our lives.
